The Freshwater master test kit is a fast, easy, and accurate test kit. It provides information on how to perform each test, how often to perform the tests, what the test results mean, and how to correct any unsafe water conditions that may be detected.

The kit is complete for testing tap water and aquarium water. It includes pH (6.0 to 7.6), high range pH (7.4 to 8.8), ammonia, nitrite and nitrate tests. The kit also includes an instruction booklet complete with information on water testing, water resistant computer calibrated color charts, test solution bottle for the five freshwater tests, and four glass test tubes with snap-tight caps in holders.
